2.1.1.1 Settings of operating mode pulse package control
Button “Temp 1“
-> Temperature switching threshold [X1]
- keypress < 3 s = current switching threshold is displayed
- keypress > 3 s = programming mode (display flashes)
- setting range -15°C…50°C, increment: 0,5 K
Button “Temp 2“
-> Time[t] (time interval)
- keypress < 10 s = current unit of time is displayed (sec.)
- keypress > 10 s = programming mode (display flashes)
- setting range 1 - 100 s, increment: 1 s.
Button “Hyst.“
-> Hysteresis [H] to temperature switching threshold
- keypress < 10 s = current hysteresis is displayed
- keypress > 10 s = programming mode (display flashes)
- setting range 0,3…5 K, increment: 0,1 K
2.1.1.2 Setting of temperature switching threshold and switching times
After setting the operation mode using the DIP switches, the temperature thresholds have to be set via the
control buttons. The relevant thresholds can be changed according to the mode of operation.
When the cover is open the set values are displayed by a short keypress of the respective keys for 3 s.
The programming mode can accessed by a long keypress (display flashes) and the setpoint can be changed
by pressing the “
+
”
or “
-
” buttons. The value, that has been changed using the method above, is saved
automatically if no button is pressed. The display shows the temperature after 3s. The current measured
temperature of sensor NTC1 is now displayed.
Recommended setting values:

H
0,5 0,5
t
40 40
Note:
The predefined parameters for H and t should only be changed in exceptional cases (bad control
response), e.g. when the temperature can not be stabilized. According to experience, increasing time [t] or
hysteresis [H] can help improving the control response.
